"The premiere of a Hollywood film featuring hydraulic fracturing is months away, but the energy industry already is preparing for battle."

"'Promised Land' stars Matt Damon as a gas-company salesman trying to lease natural-gas drilling rights in rural Pennsylvania, where fracking has become a widespread, though sometimes controversial, technique to release natural gas from shale deposits.
